[rpabani]

Hi

Thanks for creating this awesome package! Can you give any guidance on how to connect to the new preprod environment instead of testnet as its no longer supported?

Hi there,

You can use Blockfrost context to connect to preprod or preview.
Example:

from pycardano import BlockFrostChainContext, Network

chain_context = BlockFrostChainContext(
    project_id="YOUR_BLOCKFROST_PROJECT_ID",
    network=Network.TESTNET,
    base_url="https://cardano-preview.blockfrost.io/api",
)

APIs url of different networks could be found here.

I get an unexpected keyword argument 'base_url' TypeError when I try this.

It looks like from the initialiser the base_url is set to None by default.

def __init__( self, project_id: str, network: Network = Network.TESTNET, base_url: str = None ):

You will need to update the version of pycardano to v0.6.1.
